Original art by SpaceHydra. I have reworked this from being a PSD to a PNG file so those without Photoshop can use this awesome UI element. I also removed the text from the buttons and made the background transparent. I have also made it so you can use it as a sprite sheet if so desired, having the light turn on and off with a mouseover perhaps?
